Whether invading your kitchen, attacking your garden, or infesting your pets, insects and other uninvited pests are a time-consuming nuisance and may even present a risk to your health. The strong chemicals found in most commercial bug-killers and repellents may further compromise the safety of your environment. So how can you win the war against pests and still keep your family safe? Consider our four R's of natural pest control: Remedies, Recipes, References, and Resources.

Remedies

There are a myriad of natural pest-control options. It's often a trial-and-error process to find the right blend or product for your situation. Listed below are some potential pest remedies.

Garlic and/or onion and/or cayenne. Liquid sprays can be made with any or all of these to help deter/kill pests inside and outside.

Cedar is often used as a moth repellent, but is also effective against other pests.

Diatomaceous earth (DE) consists of fossilized remains of diatoms, a type of hard-shelled algae. DE is effective against insects with an exoskeleton. Be sure to choose food grade.

Pyrethrum. Pyrethrum powder comes from ground chrysanthemum flowers and contains pyrethrin, a natural pesticide. This is not the same as pyrethroid, which is a synthetic pesticide. (Cats are sensitive to low doses and some may be allergic to pyrethrum.)

Borax and all derivatives. Borax is a natural compound with powerful dehydrating affects and a wide range of applications as a pesticide. Borax is a toxin and must be used cautiously when children and pets are nearby. (See our Borax: Friend or Foe? article for relevant safety information.)

Neem oil. The key insecticidal ingredient found in the neem tree is azadirachtin, a naturally occurring substance that disturbs or inhibits the development of insect eggs, larvae, or pupae. Diluted neem oil sprayed on plants can control aphids, moth larvae, spider mites, whiteflies, and Japanese beetles. It will not harm insects that do not chew the leaves, like butterflies, ladybugs, and bees.

Essential oils.Peppermint, lavender, lemongrass, eucalyptus, basil, and clove are just a few of the effective oils.

Grind the ingredients into a powder using a blender or mortar and pestle. Dust along affected areas.

Homemade Ant Trap

1 tbsp. hot water

1 tbsp. honey or sugar

1/2 tsp. borax

Place the ingredients in a small glass jar and shake to mix. Soak a cotton ball in the mixture, slightly squeeze out the excess liquid, and put the cotton ball on a small lid. Place the ant trap where you see the most ants. After the ants have disappeared, discard the cotton ball and keep the lid for reuse.

Neem Oil Insectide

1 qt. warm water

2 tsp. dishwashing liquid

5 tsp. neem oil

Mix water and dishwashing liquid. Slowly add the neem oil while stirring the mixture vigorously. Don't prepare more of the neem oil insecticide than you'll need, as it will lose its potency if stored. (1 oz. neem oil mixed with 10 oz. coconut oil makes an excellent mosquito repellent!)

Pour an inch or so of apple cider vinegar into the bottom of a wide-mouth jar. Make a funnel with a sheet of white paper with a 3/4-inch hole on the bottom. The bottom should not touch the vinegar. Place the funnel into the jar and tape edges to secure the funnel to the jar. Effective against fruit flies and gnats.

Aphids: Spray streams of water onto plants to dislodge heavy concentrations of aphids. Use a mixture of castile soap and water to spray on smaller concentrations; the soap will dry out their exoskeleton and dehydrate them. Add peppermint essential oil for added potency. Garlic spray can also be effective.

Beetles: Pyrethrin, neem oil, peppermint, thyme.

Box Elder Bugs: Plant-based essential oils such as lavender, eucalyptus, cinnamon, citrus, and tea tree oil are effective natural repellents. Citrus oil is caustic to the exoskeleton and can also work as a pesticide.

Spiders: Spiders help keep the pest population at bay, but too many spiders can be unnerving—to say nothing of the poisonous ones. Diatomaceous earth is effective because as spiders walk across it, the razor-sharp microscopic fossils penetrate the exoskeleton, causing the spider to dehydrate and die. Suggested spider repellents include essential oils such as tea tree, eucalyptus, citronella, and peppermint.
